Quantity One User Guide
2-24
In multiple-user situations, the preferences and settings are associated with individual
user names. Under Windows, your user name is the name you use to log onto the
computer. On a Macintosh, your user name is the Owner Name on the File Sharing
control panel.
If you do not log onto your Windows PC or do not have a Owner Name on your
Macintosh, then you do not have a user name and your preferences and settings will
be saved in a generic file.
